Related Posts for WordPress Premium is an add-on to Related Posts for WordPress. Keep both plugins installed and active. Premium adds controls for matching and displaying recommendations, with manual editing for individual posts.

Set up and review related links

Open Settings > Related Posts, select how many related posts each post should have, then start the installer. It analyzes posts and makes links in the background while showing progress, so you can leave the settings page while it runs. The plugin stores links in its own tables; displaying recommendations reads the saved links instead of repeating the matching work for each user request.

The matching system compares each post’s 25 most telling words. Title words and tags count five times, categories count ten times, and linked posts also inform the match. Common words shared by many posts carry less weight, and language-specific lists ignore common words in 57 languages. Premium lets you adjust how much each matching factor counts and see why posts are related. It can also link newly published posts to older posts right away and on a schedule.

Review recommendations from a post’s editing screen. Add, edit, or remove related posts when an automatic match does not fit. Links added by hand keep their place when the extension rebuilds its automatic links.

Choose how recommendations appear

Premium includes a styling configurator, custom CSS settings, and overwritable templates. It works with links across custom post types and lets you use custom taxonomies when matching content. WordPress Network and Multisite setups are supported.

Display recommendations in a sidebar with the widget, within content using [rp4wp], or in a theme with rp4wp_children();. Add a limit such as [rp4wp limit=1] to control the number shown. The shortcode also supports an offset, for example [rp4wp limit=3 offset=3], to skip the first results.

In the settings, set excerpt length to zero to conceal excerpts. To disable automatically output CSS, clear the CSS field or use add_filter( 'rp4wp_disable_css', '__return_true' );. Premium also includes priority email support.
